The robbery was reported about 2:25 a.m. Tuesday in the first block of Elmira Street, just south of Industrial Street.

Authorities arrived to find two men and a woman suffering from gunshot wounds and transported them to San Francisco General Hospital.

Investigators determined that three suspects had broken into the home, which was occupied by a 37-year-old man, his 31-year-old wife and their two young children, police said.

When the couple confronted the suspects, they were both shot. The woman was shot in the chest and suffered life-threatening injuries while her husband was shot in the leg and was expected to survive, police said. The children were unharmed.

During an altercation, one of the suspects was also shot and succumbed to his injuries later that day. He has been identified by the medical examiner’s office as 24-year-old San Francisco resident James Smith.

The other two suspects fled and had not been found as of Friday morning, police spokesman Sgt. Dennis Toomer said.

Anyone with information about the case is encouraged to call the Police Department’s anonymous tip line at (415) 575-4444 or to send a tip by text message to TIP411 with “SFPD” in the message.
